Why do all successful sexual relationships seem to exist at the expense of others?

All relationships for that matter...I'm not talking about the person you have been going out for since middle school, or someone who was introduced to you through some secondary channel...I'm talking about the real deal..whether its college or the bar scene...or wherever...its like its a turn on for women when they are making someone jealous or destroying someone emotionally...and please dont tell me all women aren't like that...because deep down you are, most dont have the social power to act of their feelings, males too...women to me are the purest form of evil that exists in our world today..they're are suppossed to mature faster than guys...but I see them as completely self-centered and mean spirited..I used to be discouraged by this in my late teens...surely all women can't be like this...sure you guys have a polished demeanor but the level of your two-facedness is shocking to me...and its ALL women...the ones who don't behave this way seem to not be true to themselves and their inherit nature...when it comes to have a relationship whith them or even a fling thats when their true colors come out...its kind of sick...used to be kind of frightening in a way..I just learned that there is no two ways about it and you just have to play the game and roll with it or get rolled over...for how beautiful some of you can be your are truly some of the most hideous creatures on this planet....you really give all your love to your children...its easy that way....and its almost like you like being hurt, you say you like being kept on your toes but for the most part you really aren't that interesting...its a double-edged sword...because I like my woman to look good but at the same time its a nightmare waiting for them to get ready and all the time and energy you spend working out, buying the perfect outfit with matching shoes and accessories, make-up...iit just sort of makes you a dull person..a lot of guys say woman are crazy and they are impossible to figure out..even women get a thrill out of being a total mystery to men....its not that difficult, women are total hypoocrites who hold you to ridiculous double standards and their emotions are all over the place...I guess this happens because they are on the rag constantly....there is no reason to figure women out, in fact there really isn't anything to figure out...this is the exact reason dudes act like some douchebags, its really the only resolve we have...just go out there and see what we can get away with and hone our skills with practice...sorry but this is just the way it is...your deranged..the whole man woman dynamic is pretty deranged...and I'm not a bitter a guy, thats just an easy way to keep people quiet from saying what they actually believe...oh your just bitter or you never had a girl or you never get laid...thats not the case at all...I guess at 27 I'm just sick of all the bs thats going on in the world and females seem to be a huge part of it....back to the actual question...its like if a girl thinks your cute or would like to pursue you...she likes to get a co-sign..."oh, hey girl...dont you think Martin is cute?" And of course if the friend your asking thinks you are in fact cute she will downplay it to. So fake...its like you cant think for yourselves...and every girlfriend I had has had at least two of her frineds like me too...but only after I started dating her...its like competitive jealously....so weak...just poor character really...like you dont even know what you are thinking...thats why you love it when we can "read your minds"....your so transparent but you think your slick...its all so phony really....like I've known for a fact that a girl has liked me just from the way she looks at you even though all you guys swear you are too slick to ever get caught, and her friend has told me she likes me, but when you go up to talk to her oor even say hi, they give you the eye roll or act disinterested....its all just so fake....everything about girls strikes me as fake...its part of your nature...I can expand on this further but I would like to hear some responses first.
